Title: Dough dividing machine - with adjustable metering piston and digital display for its position
IPC: A21C5/02
Filed: 1979-12-13
Abstract: A dough dividing machine is equipped with a measuring chamber containing a metering piston with an adjustable stroke which is displayed on an indicator. The desired stroke of the metering piston is set by a pushbutton operated reversible motor which drives a spindle with a friction clutch and gear. A potentiometer, coupled to the gear, feeds the indicator which is a minicomputer with a digital display. A motor drives the spindle through a friction clutch and gears. The gears actuate a potentiometer which feeds a minicomputer with a digital display. The metering piston is moved by the ejector lever, to vary the volume of the measuring chamber. A nut on the spindle limits the movement of the ejector lever in one direction, and a nut limits it in the other direction by stopping the blade lever which is linked to the ejector lever. This requires only one weighing operation to find the s.b. of the dough. The computer multiplies the volume setting with the correct factor on this basis.

Title: Integrated logic gate with current amplification - has screen zone extending deep along part of transistor base zone, adjacent injector zone
Inventor: KELLER HANS DIPL ING
IPC: H01L27/02
Filed: 1980-09-17
Abstract: The integrated logic gate has an injector zone and a screening zone, surrounding the rectangular base zone of the vertical transistor of the gate. Thus between the injected zone and the parallel, adjacent side of this transistor base zone an effective base zone of the lateral transistor of the gate is formed. The screening zone (1) extends also along at least a part of the side of the vertical transistor (Tv) base zone (3) adjacent to the injector zone (2). The extension runs deeper than the depth of this transistor base zone. Thus the minority discharge carrier current is concentrated on a part of this base zone, adjacent to the injector zone. This forms an effective base zone (4) of the lateral transistor (1), which is narrower than the base zone side of the vertical transistor (1), which is narrower than the base zone side of the vertical transistor, adjacent to the injector zone. The injector zone and/or the adjacent base zone of the vertical transistor have pref. each a zone extension, restricting the lateral transistor base zone width.

Title: Incremental brake pressure switch
Inventor: ENGELBRECHTEN HEINZ V
IPC: B60Q1/44
Filed: 1981-02-18
Abstract: Hydraulic-electric brake pressure switch which is to be retrofitted in motor vehicles and which permits incremental switching on of the brake lights as a function of the braking pressure in motor vehicles with four brake lights. Switches which are installed at present permit the brake lights to light up as soon as the driver puts his foot on the brake pedal but is not yet braking that is to say even in the ready-to-brake state. When traffic backs up, this results in fatigue phenomena which leads to apathy. An actual braking manoeuvre is distinguished too late from the actual ready-to-brake state and leads to a rear-end collision. A visible difference is to be made possible between the ready-to-brake state, weak braking or strong braking. The described incremental brake pressure switch is set permanently to different brake pressures in an infinitely variable fashion so that the four brake lights light up successively in incremental fashion after the actual braking process and the application of pressure to the brake pedal. Retrofitting is possible on any vehicle by any motor vehicle mechanic without changing the brake components installed by the manufacturer.

Filed: 1981-05-22
Abstract: What is to be provided is an espagnolette fastening which makes it possible to bring a door or gate into the closed position as a result of the pivoting or displacement of the latter and to block it in this position, without having to actuate the actual lock to achieve this. An espagnolette fastening of this type is characterised in that it is freely resilient, in order to be able to assume the spring-loaded opening position in relation to the follower (28) in its closing position. For this purpose, the espagnolette fastening has a spring-loaded latch (63) at the free ends of the espagnolettes. The follower (28) has a lifter for each espagnolette, in order to pull the espagnolette into the opening position. The connection of the follower (28) to the espagnolette is made via a driver (33) which is fastened to the espagnolette and which is in slide-displaceable driving relationship with the follower. At the same time, the driver has a pin which is arranged transversely to the direction of movement and which, in the closing state of the follower (28), is mounted astride in the lifter so as to be longitudinally displaceable, in order to cause the espagnolette to act as a latch. <IMAGE>
